| 摘要: |
| 应水反应金属燃料发动机启动过程对水流量的苛刻要求，提出一种新型反压自适应恒流喷嘴。理论分析此喷嘴的流量自适应保持原理，通过流量特性实验验证此喷嘴能够自动调节流阻，实现流量恒定。 |

| Abstract: |
| Under the severe demand of the Water/Metal Fuel Motor on the flux of water in the starting period, a new type of pressure-adaptiveand flux-constant orifice was brought forward. The flux-constant principle of this orifice with pressure-adaptability was analyzed theoretically. Experiments were carried out. Their results show that the orifice can satisfactorily adjust the flux resistance automatically and keep the flux constant. |
